Abstract
Interlayer coupling between Fe layers and magnetoresistance effect hav e been investigated in Fe/Cr/Fe/Ni-Fe/NiO sandwiches. The interlayer c oupling between two Fe layers oscillates as the thickness of Cr layer changes. The strongest antiferromagnetic coupling is observed when the thickness of the Cr layer is 1.2 nm. The highest magnetoresistance ra tio due to spin-dependent scattering is only 0.43%. The low magnetores istance ratio is thought to be caused by high resistivity of the Cr la yer.
